By cooling down the camera up to 35°C below ambient, the already low noise characteristics can be further reduced. By increasing gain (like the ISO setting of DSLR cameras), you can reduce exposure times to below 30 seconds. Effects from seeing or inaccuracies of the drive are therefore eliminated.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eLunar and planetary images: Extremely short exposure times (due to high sensitivity) freeze the seeing. Through the high resolution of the sensor, many details can be reproduced even at shorter focal length. Video astronomy is also possible.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eImportant: external power supply is required!\u003c\/em\u003e\u003cbr\u003ePlease notice that all ZWO cameras with a cooling system need to be connected to an external 11-15V power supply to work. Even when the cooler is not being used the power supply must be used for the camera to be reliably recognized.\u003c\/p\u003e\n\u003cp\u003eThese cameras are not airtight, so if the camera remains on the telescope, it is exposed to moisture. The small amount of desiccant in the camera can protect the sensor and the inside of the protective glass from moisture for the duration of the exposure, but not for days on end. Moisture problems can be the result. A simple trick is to stretch a plastic bag around the focuser to which the camera is attached so that no air can get in. Silica gel is placed in a small cloth bag inside the plastic bag. This will also create a \"dry climate zone\" for the camera on the telescope. This allows you to leave the camera on the telescope for a few days for an imaging session lasting several days.\u003c\/p\u003e\n\u003cp\u003eIn the medium and long term, however, this is no substitute for proper storage in an airtight case with silica gel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSensor: 4\/3\" CMOS Sony mono IMC492LLJ - back illuminated\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eResolution: 11.7 megapixels, 4144 x 2822 (2x2 Binning)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eResolution: 46.8 megapixels, 8288 x 5644 (1x1 Binning)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePixel size: 4.63 µm (2x2 Binning), 2.32µm (1x1 Binning)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSensor size: 19.1mm x 13.0mm - 23.2mm diagonal\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eExposure time: m32µs to 2000s\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMaximum frame rate at full resolution: 16.3 fps\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eQE: up to 90%\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFull Well: approx. 66 ke-\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eReadout noise: 1.2 to 7.3e-\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eADC: 14 bit\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSensor protection: Protective AR glass\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCooling: Peltier cooling up to 35°C below ambient\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSoftware demands: USB 3.0 should be supported by operating system\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCache: 256 MB DDR3 cache\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTelescope connection: T2, 2\" and 1.25\"\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDistance T2-thread (female) to sensor: 17.5mm (6.5mm without adapter)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDimensions: 78mm diameter and 73.5mm length (without 4mm male T2 thread)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWeight: 410g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eWhats included:\u003c\/em\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cem\u003eASI camera cooled, with 11mm T2 ring\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCamera bag\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eUSB 3.0 cable, 2m\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eQuick Guide (English)\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eT2 extension (21mm long)\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eM48 to T2 adapter (16.5mm long)\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eAdapter from T2 to 1.25\" socket with filter thread\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDust cap 1.25\"\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eM42-M48 adapter (without optical path)\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003e2x USB 2.0 cable, 0.5m\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFlat adapter T2 to 1.25\" thread (without optical path)\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003e4x spacer ring\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/div\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003eDownload the ASI 294MC-P Manual \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/files\/ASI294_Manual.pdf?v=1632381964\" target=\"_blank\"\u003ehere\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eDownload the latest Camera Driver from ZWO \u003ca href=\"https:\/\/astronomy-imaging-camera.com\/software-drivers\" target=\"_blank\"\u003ehere\u003c\/a\u003e\u003c\/p\u003e","brand":"ZWO","offers":[{"title":"Default Title","offer_id":54078634131791,"sku":"ASI294MMPRO","price":2125.12,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/files\/ZWO-ASI-294MM-AstroCamera_6.jpg?v=1735317552","url":"https:\/\/www.horizonastronomy.ie\/en-ro\/products\/zwo-asi-294mm-pro-colour","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
